This study examines the static behavior of carbon nanotube-reinforced composite solid plates under uniform transverse loading using three-dimensional isogeometric analysis. The implementation of the NURBS shape function helps avoid the shear locking phenomenon. To evaluate the accuracy and convergence of the method, this study examines several mesh densities and different orders of NURBS shape functions. Special attention is given to how the number of elements through the plate’s thickness affects the results. The results demonstrate that, similar to those of previous studies, results can be achieved with third-order NURBS functions and only a few elements in the thickness. These results reveal that 3D IGA can be an effective and accurate method for simulating CNTRC structures. Overall, the study provides practical guidance on selecting suitable discretization strategies when analyzing the mechanical behavior of CNT-reinforced plates.

摘要

This study examines the static behavior of carbon nanotube-reinforced composite solid plates under uniform transverse loading using three-dimensional isogeometric analysis. The implementation of the NURBS shape function helps avoid the shear locking phenomenon. To evaluate the accuracy and convergence of the method, this study examines several mesh densities and different orders of NURBS shape functions. Special attention is given to how the number of elements through the plate’s thickness affects the results. The results demonstrate that, similar to those of previous studies, results can be achieved with third-order NURBS functions and only a few elements in the thickness. These results reveal that 3D IGA can be an effective and accurate method for simulating CNTRC structures. Overall, the study provides practical guidance on selecting suitable discretization strategies when analyzing the mechanical behavior of CNT-reinforced plates.
